| contents | CONSTRAINING THE DETERMINATION OF THE STAR FORMATION HISTORY OF GALAXIES G. Magris Física, Astronomía y Matemáticas stars: formation Galaxies: evolution We explore the ability of two di erent algorithms, GASPEX and DinBas2D, to derive the Star Formation History from a galaxy spectrum. The former is a non-parametric method which derives the galaxy mass fraction formed in a pre-selected set of epochs. The second is a new approach that nds the best combination of age and mass fraction of two simple stellar populations that ts the target spectrum. In order to constrain the advantages and limitations of this novel method, we apply it to simulated galaxy spectra that cover the Hubble sequence. 2009 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57115758062 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.35 |
